Hi,
I need to create an EOFetchSpecification for an entity where by
the objects returned are grouped on a key that is found through a
relationship.
Does anyone have a suggestion?
Don't? A fetch of EOs that are subject to a GROUP BY or other
aggregate function are not EOs any more, they are just data. This is
something that raw rows can be used for, but you will still need to
get EOF to generate the SQL. Project Wonder has support for
aggregate operations, but I don't recall the class name(s). You will
probably also find examples on wocode and wodev / the WOKI (or
whatever the WO wiki is called, wookie? :-P
